- B48B20T At the beginning of May 2014, this is the most powerful version of the efficient 4-cylinder BMW engine, which is installed on production cars with a gasoline unit. This engine is available on the BMW 330i F30 and xDrive LCI.
- B48A20 This 2.0-liter more powerful engine is installed in the same 2-series 225i Active Tourer F45 minivan, including the 225i xDrive all-wheel drive version. Since October 2015, the engine has been installed on the second-generation BMW X1 crossover - F48 xDrive25i
SpecificationsThe power unit was a product of reliability and this is not unfounded, because it was put on a wide range of BMW cars. This engine was produced by BMW Plant Hams Hall, and the engineers named it serial number 20. The cylinder block was made of aluminum. "Used" exclusively 95 and 98 gasoline, had an in-line configuration with four cylinders. The two-liter engine produced 190 horsepower at 5,000 rpm. As for the torque, from 270 to 350 Newton meters, at 4600 rpm to 4800, respectively. The engine used technologies of the European standard Euro-6.
OilsMotorists were content with fuel consumption of 9 liters per city, when driving on the highway, they were content with six liters per 100 km, and the combined cycle pleased seven liters of 95 or 98 gasoline. As for oil, for every 100 kilometers, the engine consumes about 700 g. Engineers recommend using branded oil 5W 30 or 5W 40. It is necessary to carry out an independent oil change or contact a car service station after 10,000 kilometers. The consumption in the article is indicated for good and high-quality German autobahns. For our roads, domestic experts recommend changing the oil after 8,000 km of run. In order not to overfill the oil, engineers also recommend pouring no more than 5 liters into the power unit.
Chip tuningThe indicators that we indicated to them above are suitable for stock cars. But since Bavaria Motors does not fully agree, and local and domestic tuning studios saw the wide potential of the engine, chip tuning of this engine is widespread, which will lead to a total power unit of about 300 horsepower. If a car is chipped at a specialized service, then, as practice and reviews show, the potential for loss of engine life is reduced to zero.
ReliabilityLet's talk about reliability. Officials at the service station say that the engine life of this model is comparable to the service standards of other cars of the same class. German engineers, in the car's operating instructions, recommend checking the gasoline installation every 10,000 km. And we're not talking about the mandatory scheduled technical inspections for every 5,000 km. And do not use the services of garage S.T.O. But this will be another article, and we continue to talk about common engine problems. As in other power units, extraneous noise and knocks may appear during prolonged operation. The reason for this is the unstable and shaky operation of the crankshaft. It is also necessary to pay attention to the exhaust manifold, which can become clogged with soot and other waste products, which directly affects the serious loss of engine power. To carry out scheduled maintenance of the engine, German engineers are allowed to independently in the garage. We mean replenishing the oil level, replacing the gasket of the main cylinder block, valve stem seals, and so on. However, major repairs must be carried out exclusively in the boxes of official service centers. In order to determine the problem in this engine, it is definitely recommended to perform scheduled diagnostics on the S.T.O. It is absolutely impossible to make a high-quality overhaul in garage conditions, it can also lead to more serious damage, and significantly increase the service bill.
OutcomeSumming up, let's say that the power units of the B48B20 series are a high indicator of German quality and reliability. These engines cannot be called millionaires, but they are able to give the driver 700-800 thousand km of a pleasant ride, taking into account the proper maintenance of the power unit, high-quality oil and combustible fuel. Average consumption rates, and the ability to tune the engine to almost 300 horsepower. At the same time, get from 270 to 350 Newton meters of torque. If you add rear-wheel drive to this mixture, for example, the BMW 5 Series, you will get incredible pleasure. See you again.
